Light Dot Sight

ABSTRACT

With a light dot sight ( 100 ) that can be affixed in the region of the surface of a breech of a firearm. The sight has a partially transparent reflector element ( 110 ) which reflects the parallel light of a light source ( 120 ) mounted on the firearm, into the eye of the shooter to focus to a point on the retina of the shooter. Obstruction of a field of view of the shooter directed to a special event is avoided in that the undersurface ( 111 ) of the partially transparent reflector element ( 110 ) has a width which has dimensions for directly and robustly anchoring the reflector element ( 110 ) in the region of the surface of the breech by means of a fastener.

CROSS-REFERENCE TO RELATED APPLICATION

Priority is claimed of German Patent Application No. DE102020113533.5,filed May 19, 2020, and entitled “Light Dot Sight”, the disclosure ofwhich is incorporated by reference herein in its entirety as if setforth at length.

BACKGROUND

The invention relates to a light dot sight which can be affixed to thesurface of a breech of a firearm with a partially transparent reflectorelement that reflects the parallel light of a light source attached tothe firearm and focused on the retina of a shooter into the eye of theshooter.

Light dot sights of the type mentioned above are used in the prior artas target devices, in particular for handguns. The known light dotsights, however, have the disadvantage that the reflector element isinserted into a usually metallic socket, by means of which the reflectorelement is anchored at least indirectly in the surface of the breech.

The metallic socket has the disadvantage that important areas in thefield of view of a shooter are obscured by the socket in such amounting, so that the shooter cannot fully perceive an event takingplace around him.

SUMMARY

The object of the invention is therefore to create a light dot sightwhich never restricts the field of view of a shooter directed to aparticular event.

For a light dot sight of the above mentioned type, this object isachieved according to the invention in that the undersurface of thepartially transparent reflector element has a width which is dimensionedfor anchoring the reflector element directly and robustly in the regionof the surface of the breech by means of a fastener.

Preferred embodiments of the invention are the subject matter of thesubordinate claims, the elements of which act in the sense of a furtherimprovement of the approach to achieving the object underlying theinvention.

With the light dot sight according to the invention, by means of thecombination of features that the undersurface of the partiallytransparent reflector element has a width which is dimensioned foranchoring the reflector element robustly in the region of the surface ofthe breech by means of a fastener, a device is created by means of whicha completely unobstructed view of an observed event is enabled for ashooter with his weapon aimed.

According to a first preferred embodiment of the light dot sightaccording to the invention, it is provided that the width of thepartially transparent reflector element in the region of theundersurface close to the breech is larger than the width of theoptically effective area of the partially transparent reflector elementremote from the breech.

As an alternative to the above embodiment, the width of the partiallytransparent reflector element in the region of the undersurface close tothe breech may have the same dimensions as the optically effective areaof the partially transparent reflector element remote from the breech,wherein due to the total thickness of the reflector element theundersurface of the partially transparent reflector element then has awidth which is sufficiently dimensioned for anchoring the reflectorelement robustly by means of a fastener.

The reflector element is traditionally formed by a plane parallel plateprovided with a partially reflective surface or by a concave/convex lensprovided with a partially reflective rear surface. In the latter case,the concave rear surface of the concave/convex lens acts like a hollowmirror as a collimator for the divergent light of the light source.

Preferably, an adhesive is provided as a fastener. Alternatively, thefastener may be formed by one or more screws that are guided at apredetermined angle through the reflector element and anchored in theregion of the surface of the breech.

Between the light source and the reflector element, a collimator in theform of a collection lens, which transfers the light of the light sourceusually formed by an LED into a parallel beam of light, may preferablybe arranged in the immediate vicinity of the light source, wherein thelight source and the collimator are combined into a robust unit, whichis anchored in the surface of the breech in front of the reflectorelement by means of one or more screws as anchoring elements or by meansof an adhesive.

According to an important preferred embodiment of the light dot sightaccording to the invention, the light source, the collimator in the formof a lens and the reflector element are combined into a robust unit,which is anchored by means of one or more anchoring elements such asscrews or adhesive in the region of the surface of the breech.

DETAILED DESCRIPTION

The light dot sights 100 according to the invention shown in FIGS. 1 and2 can be attached in the region of the surface of a breech 200 of afirearm and each contains a partially transparent reflector element 110,which reflects the parallel light of a light source 120 attached to thefirearm and focused to a point on the retina of the shooter's eye intothe eye of the shooter.

The undersurface 111 of the partially transparent reflector element 110has a width which is dimensioned for anchoring the reflector element 110robustly in the region of the surface of the breech 200 by means of afastener.

The width of the undersurface 111 of the partially transparent reflectorelement 110 is dimensioned for anchoring the socketless reflectorelement 110 robustly in the region of the surface of the breech 200 bymeans of a fastener acting directly on the reflector element 110.

According to the embodiment of the present invention shown in FIG. 1,the width of the partially transparent reflector element 110 in theregion of the undersurface 111 close to the breech has the samedimensions as the optically effective regions of the partiallytransparent reflector element 110 remote from the breech, wherein due tothe total thickness of the reflector element 110, the undersurface 111of the partially transparent reflector element 110 has sufficient widthfor anchoring the reflector element 110 robustly in the region of thesurface of the breech 200 by means of an adhesive.

The reflector element 110 is formed by a concave/convex lens providedwith a partially reflective rear surface, wherein the concave rearsurface of the concave/convex lens acts similarly to a collecting lensas a collimator 130 for the divergent light of the light source 120.

According to the embodiment of the present invention shown in FIG. 2, acollimator 130 is arranged between the light source 120 and thereflector element 110 designed as a plan-parallel plate, which transfersthe light of the light source 120 into a parallel light beam, whereinthe light source 120, the collimator 130 and the reflector element 110are combined into a robust unit 140, which is anchored in the surface ofthe breech 200 in front of the reflector element 110 by means of anadhesive as anchoring elements.

The embodiment of the invention explained above is used only for thepurpose of a better understanding of the teaching according to theinvention specified by the claims, which as such is not restricted bythe exemplary embodiment.
